The most ive worn were 10 diapers along with 3 baby diapers (as stuffers). I wore some depends maximum protection along with 2 different CVS brand adult diapers and 3 pampers (i think they were pampers.. i dont remember) the diapers sizes were medium, large, and extra large. I tried to divide them up equally. any ways i wet them about 4 times (heavy each time) . they just ended up leaking around the inside of the leg area . When i manged to slip them off i checked and i think they only got through the first 4 adult diapers. im wearing 2 dry 24/7 right now and they seem to work a lot better then that other time. They're very absorbent
